I agree and disagree. As an operation person, I think we need to make an argument for why X can't be done right away, but we must have a plan Y for migration. I know for a fact there is still some ancient database server running in our data center serving our critical business but there's a plan to migrate that to modern databases. While re implementing everything is costly, company has to hire specialist from a specific consulting firm to support such ancient database, and how long can we retain such talent without spending extreme amount and caution? "I am scared if I did this will screw everything up." There will be a point they have to migrate such database to something modern, and the cost is still several million plus. The same argument that corporate world doesn't allow Python 3 or has a hard time to migrate to Python 3 because machines are running on some ancient RHEL servers or because of some security requirement. I get it and I don't get it. First, let's ditch RHLE. Fuck that. I really don't see reason to use RHLE; fine, YMMV. But it is people's job to do work. Some pieces can die, and some pieces will have to evolve, either from scratch, or slowly.
